Lighting  
Entry lighting can be disabled manually by  
closing all doors, pressing Q on the remote  
key, or starting the vehicle.  
Battery Load Management  
The vehicle has Electric Power Management  
(EPM), which estimates the battery's  
temperature and state of charge. It then  
adjusts the voltage for best performance  
and extended life of the battery.  
This feature can be changed. On the  
infotainment home page, select Settings T  
Vehicle T Vehicle Locator Lights.  
When the battery's state of charge is low,  
the voltage is raised slightly to quickly bring  
the charge back up. When the state of  
charge is high, the voltage is lowered  
slightly to prevent overcharging. The  
voltmeter gauge or the voltage display on  
the Driver Information Center (DIC),  
if equipped, may show the voltage moving  
up or down. This is normal. If there is a  
problem, an alert will be displayed.  
Exit Lighting  
Some exterior lamps and interior lamps turn  
on when the driver door is opened after the  
vehicle is turned off.  
Press the lamp lens to turn the rear reading  
lamps on or off.  
Lighting Features

for a set amount of time, then automatically  
turn off.  
Entry Lighting  
The interior lamps turn on when pressing K  
on the remote key or opening any doors,  
and the dome lamp control is in the door  
position.  
The interior lights turn on when the vehicle  
is turned off.  
The battery can be discharged at idle if the  
electrical loads are very high. This is true for  
all vehicles. This is because the generator  
(alternator) may not be spinning fast  
enough at idle to produce all the power that  
is needed for very high electrical loads.  
The exterior lamps turn off immediately by  
turning the exterior lamp control off.  
Some exterior lamps also turn on when

pressing K on the remote key or opening  
any doors. Low-Beam lamps will only turn  
on briefly at night, or in areas with limited  
lighting.

the following are on, such as: headlamps,  
high beams, fog lamps, rear window

heated seats, engine cooling fans, trailer  
loads, and loads plugged into accessory  
power outlets.  
Exterior Lighting Battery Saver  
EPM works to prevent excessive discharge of  
the battery. It does this by balancing the  
generator's output and the vehicle's  
electrical needs. It can increase engine idle  
speed to generate more power, whenever  
needed. It can temporarily reduce the power  
demands of some accessories.  
The exterior lamps turn off about 10 minutes  
after the vehicle is turned off, if the parking  
lamps or headlamps have been manually  
left on. This protects against draining the  
battery. To restart the 10-minute timer, turn  
the exterior lamp control to the O position  
and then back to the ; or 2 position.  
Normally, these actions occur in steps or  
levels, without being noticeable. In rare  
cases at the highest levels of corrective  
action, this action may be noticeable to the  
driver. If so, a DIC message might be  
displayed and it is recommended that the  
driver reduce the electrical loads as much as  
possible.  
To keep the lamps on for more than  
10 minutes, the vehicle must be on or in  
accessory mode.  
Battery Power Protection  
This feature helps prevent the battery from  
being drained if the interior courtesy lamps  
or reading lamps are accidentally left on.  
If any of these lamps are left on, they  
automatically turn off after 10 minutes if the  
ignition is off. The cargo lamp shuts off  
after 20 minutes if the ignition is off.  
The lamps will not come back on again until  
one of the following occurs:
